Firstly, p-methylacetophenone was obtained in the presence of alchlor as the catalyst, and the optimum condition was 4:1:2 in molar ratio for toluene, acetic anhydride and alchlor with yield of 86.2%.

首先，以和乙酸酐为原料，催化剂三氯化下合成对乙酮，并确，乙酸酐和三氯化的最佳摩尔比为4: 1: 2，收率为86.2%。

Solid acid alchlor catalyst was prepared from anhydrous aluminium trichloride through liquid solid solvent method,with pretreated bentonite as support.

以无水三氯化为原料,并以处理过的膨润土为载体,采用液固溶剂法制备固体酸催化剂。
